The scoop on Triceratops vs. Torosaurus

Big Cretaceous Era news out that a couple of paleontological nerds have determined that Triceratops is actually just a juvenile Torosaur, so that Trike "never really existed". But as the Examiner notes, the name that is going to go away is Torosaurus; because the Triceratops name came first (by two years), that's the name that sticks. So all Torosaur fossils will be relabeled Triceratops fossils, even though Trike is just a young Toro. Got that?

To make this clearer, I grabbed two images and arranged them adjacently, Trike on the top, Toro on the bottom. The idea is that as Trike matured, the frill got bigger and developed apertures.

Believable? Well, for one thing, it looks like the horns got worn down, if the Toro really is the adult Trike.
